XOR
Gets the exclusive disjunction (XOR) of two expressions.
Format
<expression1> XOR <expression2>
Parameter
Return value
Returns the XOR value as an integer value.
Description
Gets the XOR value of the expressions specified in the <expression 1> and <expression 2> parameters.
(Each bit of the two expressions is computed separately.)
When the values of the <expression1> parameter and <expression2> parameter are double precision real
values, the decimal part is rounded off.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a value outside the range -2147483648 to 2147483647 is specified as an integer parameter, an "Overflow"
error will occur.
If a value is assigned to the return value variable or the variable is not used in an expression, a "Syntax error"
error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• None.
Example
Gets the XOR value of 12 and 31.
The result is shown below.
